Description
The ATA5278 device is an integrated BCDMOS antenna driver IC dedicated as a
transmitter for Passive Entry/Go (PEG) car applications and for other hands-free
access control applications.
It includes the full functionality of generating a magnetic LF field in conjunction with an
antenna coil to transmit data to a receiver in a key fob, card or transponder. A micro-
controller can access the chip via a bi-directional serial interface.
